im currently bound to 1.14.x AND 1.12.20 but

tried with cmake and

-DCMAKE_CXX_FLAGS="-g -fno-omit-frame-pointer -fsanitize=thread"
-DCMAKE_C_FLAGS="-g -fno-omit-frame-pointer -fsanitize=thread"
-DCMAKE_EXE_LINKER_FLAGS="-fno-omit-frame-pointer -fsanitize=thread"
-DCMAKE_MODULE_LINKER_FLAGS="-fno-omit-frame-pointer -fsanitize=thread"

giving working TSAN results for both versions


i think DCMAKE_CXX_FLAGS and DCMAKE_EXE_LINKER_FLAGS not needed here


thanks
